The gravitational interaction between celestial bodies in our solar system gives rise to the well-known tidal waves at the planets. The tidal waves that originate at the Earth's crust perpetually transform the microstructure of the Earth's crust leading to a variation of the concentration of natural radioactive gases in the terrestrial air and to varied conditions of their leakage to the Earth's atmosphere.
These variations give rise to bursts of thermal and slow neutrons in the vicinity of the Earth's crust because the radioactive gases are the sources of energetic alpha particles that induce neutron production upon the interaction with the nuclei of elements of the Earth's crust and the atmosphere. In this process, the idea of the production of the neutron in the ground coat is extended to the other celestial bodies interacting with one another.
The celestial bodies or the celestial objects are the elements that are located outside the earth’s atmosphere. The celestial bodies will be far away from the earth and the distance measured will be in light-years. The best example for the celestial bodies is the moon, mars, all the planets, stars, etc., all together form the universe. The glorious starry night sky is filled with such objects and when we observe them with a telescope, they reveal fascinating aspect and beauty of the worlds of their own. Since all the celestial bodies are so far away, we cannot observe all of them using the naked eye and hence we depend upon telescopes to study and observe them.
What are Celestial Bodies?
The celestial bodies are the objects located outside the earth’s atmosphere, for example, Moon, Stars, etc., further all the celestial bodies are classified into the following types.
Stars are the giant balls in space made of hot gases that can produce and illuminate their own light. Stars release energy by converting Hydrogen gas into Helium gas in their cores. Stars are giant in size and have an immense gravitational attraction force between them. The sun is a medium-sized star that gives us solar energy and makes life possible on earth.
The planets are nearly large spherical objects that revolve around the sun. Planets move in the fixed orbits around the sun. There are 8 planets in our solar system. Planets may be made of rocks, metals and gases like hydrogen, nitrogen and methane. The earth is also one of the planets in our solar system and is the only known place in the universe that supports life. Planets that revolve around other stars are known as exoplanets.
Satellites are objects that revolve around the planets. They form an essential part of the celestial bodies. Satellites may be of natural origin or man-made known as the artificial satellite. The moon is a natural satellite of the earth, it revolves around earth because it is bound by the Earth’s gravitational pull. Scientists also placed artificial or man-made satellites around the earth and other planets for various purposes and to study them in detail.
Comets are the small pieces of ice and rock that come from the outer edge of the solar system. When the orbit of comets brings it closer to the sun, the ice on them vaporizes, creating a beautiful trail behind them. Hally’s comet was the most beautiful comet witnessed by human beings.
The Asteroids are small irregularly shaped rocks made up of metal or minerals that orbit the sun. Most of the asteroids are found between Mars and Jupiter in the region known as the asteroid belt.
Galaxies are large groups of stars held together by gravity. The sun and the solar system is part of a galaxy known as the Milky Way. Other galaxies are usually so far away that they look like stars in the night sky. The Andromeda galaxy and the Large Magellanic Cloud are galaxies that can be seen with the naked eye on a clear night.
Did You Know?
There are around 400 billion stars in the galaxy and as many as 500 billion galaxies in the Universe.
A dying star is called a White Dwarf. This happens when a star has burned up all of its nuclear fusion. It then turns into just a large clump that will emit light until it finally fades away.
